$NH_4^+$

Vedclass · Answer

(B) The correct answer is $(B)$.In the ammonium ion $(NH_4^+)$,the nitrogen atom is covalently bonded to three hydrogen atoms.The fourth hydrogen ion $(H^+)$ is attached to the nitrogen atom via a coordinate (dative) bond,where the lone pair on nitrogen is shared with the $H^+$ ion.Since the entire species carries a positive charge and exists as an ion,the interaction between the $NH_4^+$ cation and any counter-anion (like $Cl^-$ in $NH_4Cl$) is electrovalent (ionic) in nature.Thus,$NH_4Cl$ contains all three types of bonds.

List-$I$ (Bond)	List-$II$ (Bond enthalpy in $kJ \ mol^{-1}$)
$(A)$ $Si-Si$	$(I)$ $240$
$(B)$ $C-C$	$(II)$ $297$
$(C)$ $Sn-Sn$	$(III)$ $348$
$(D)$ $Ge-Ge$	$(IV)$ $260$
